Lotto bosses have urged the winner to come forward after a week of silence

Andy Carter, Senior Winners’ Advisor at The National Lottery said: “Instead of enjoying their massive £76m windfall, the lucky ticket holder has already let a week slip by, and may be going about their everyday routine completely unaware of their amazing change of fortune.

"The ticket was bought in-store so you should check the places you usually keep your tickets and make sure you’ve checked them all in case you’re the missing winner.

"We have the champagne on ice and our fingers crossed that the lucky winner comes forward to claim their win soon.

“Our player services team are on standby waiting for the ticket-holder to come forward.

"They have great expertise in helping winners embrace life-changing wins and making sure that they are able to start to enjoy their new found wealth as quickly as possible.

"They will be on hand every step of the way to guide the ticket-holder through the winning experience.”

Claiming the jackpot would put a single ticket-holder in the same league as pop star Ed Sheeran, worth £80 million.
